A raw food diet creates major improvements in health. The reasons are not known, but the experience is unmistakable. Weight normalizes, which generally means a reduction in fat. At the same time, a person feels extremely energized. It's as if energy would rather be burned up than converted to fat.
There seems to be a major shift in physiology which makes one feel highly energized from raw food. I can only theorize why this occurs. It is quite likely that a large part of cooked food can only go into fat production, because heat and acid alter it making it unmetabolizable in other complex processes. By contrast, raw food should break down into components which can be directly metabolized in a variety of cells.
